Step 2: Identify the Leak Source
- Check the water tank for cracks or damage. Even small fractures can cause leaks.
- Inspect the water inlet valve and tubing for looseness or damage.
- Look under the machine for pooled water or damp spots indicating the leak’s origin.
- Examine seals around the brewing unit and water pathways for wear or misalignment.
If you notice any damaged parts, replace them before proceeding.
Step 3: Tighten, Replace, or Seal Components
- If a seal or gasket appears worn or cracked, replace it with an appropriate part, such as a new water seal or gasket.
- Ensure all hoses are tightly connected and free of cracks or kinks.
- Secure any loose fittings and verify the water tank is properly seated and sealed.
Use manufacturer-approved replacement parts for best results.
Step 4: Test After Repairs
After completing repairs or adjustments, reassemble the machine, fill the water tank, and plug it back in. Turn on the machine and run a short brew cycle or rinse to check if the leak persists. Observe carefully for any signs of water escaping.
If the leak continues, revisit the previous steps to ensure all parts are correctly installed or consider replacing additional components.
Step 5: Prevent Future Leaks
Regular maintenance is key to preventing leaks. Descale your machine periodically using a descaling solution like the De’Longhi EcoDecalk, which is effective and eco-friendly. Replace the water filter regularly to reduce mineral buildup that can cause blockages and pressure issues. Always ensure the water tank is properly fitted and free of cracks before each use.
Address small leaks promptly to prevent more significant damage, and consider professional servicing if problems persist.
